It should return the buffer whose buffer-file-name is that of the file.
I think in your case, that should be the dired-style buffer and *also*
the buffer from which cpio-mode was called (i.e. the buffer which
originally held the file's content).
In RMAIL we satisfy these constraints using buffer-swap-text.
